822d9b83 - Do not create sigwait() thread when JL_OPTIONS_HANDLE_SIGNALS_OFF (#48957)

Do not create sigwait() thread when JL_OPTIONS_HANDLE_SIGNALS_OFF (#48957) We already disable part of the signal-handling machinery, but it seems that this piece was missed for an unknown reason. This is important to disable so that, e.g. `sigwait()` can be received reliably by the main application (which may even be another copy of Julia).
